Hello everyone,
I have to perform an harmonic analysis and I need to calculate not only the module of the harmonic but its phase too. How can I obtain it by SimView?

    In Simview, first, click "Perform FFT" to display the amplitude of the harmonics.

    Then, add another screen. In the new screen, click "Add/Delete Curves...".

    On the left-hand side of the list "Variable Available", choose "Angle". The phase of the harmonics will be displayed. "Angle(D)" displays he phase in degrees, and "Angle(R)" displays phase in radian.
